SFT SOL B/CIRC

DESCRIPTION
Shift solenoid valves A and B are turned "ON" or "OFF" by the TCM in response to signals sent from the inhibitor switch, vehicle speed and throttle position sensors. Gears will then be shifted to the optimum position.






TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.






ON BOARD DIAGNOSIS LOGIC
